HANS G. HANSON, OF LACLEDE, MISSOURI.

COEN-PLANTEIR.

T0 aZZ whom 'it may concern: v

Be it known that I, HANS C. IIANSON, a citizen 0f the Unitecl Stabes,residing ab Laclecle, in the county 0f Linn and State 01 Missouri, haveinvented certain new ancl useful I1nprovements in Corn-Planters, ofWhich the following is a specification, reference being had to theaccompanying draw- 1ngs.

'1his invention relates to certain new and usef'ul improvements in cornplanters ancl has f01' its object to provicle a machine of thischaracter 0f comparatively simple C011- struotion, whereby the corn maybe intermittently cl1oppecl ancl planted in rows 01' hills, saiclmachine being providecl with a suitable marking element vvhereby saidr0ws may be plantecl parallel with ea'ch other.

A further object is to provide nevv and novel means for mount-ing thesee0l boxes and furrow opening shoes, ancl to provide means f01adjusting tl1e Same whereby the sh0es may be raised 01 lowerecl t0regulate the depth to Wl110l1 the seecls are deposited in the seil.

VVith these and other objects in view, t-he invention consists 0f tl1enovel features of const-ruction ancl tl1e combinalvion and a1- 1angement0f arts hereinafter fully describecl and clai1ned, a'nd illustrated inthe accompanying drawings, in whicl1 Figu1e 1 is a sicle elevation 0'f acorn planter constructecl in accorclance Willi the preserit invention;Fig. 2 is a top plan view thereof'; Fig. 3 is a section taken on theline 33 0f Fig. 2; Fig. 4 is a.section haken on the line 44 of Fig. 2,anc1 Fig. 5 .is a detail perspective view of one encl of the seecldropping i0ck shaft.

Refer1ing t0 the clrawings 5 inclicates a wheel supporting shaft 01"axle up0n eacl1 end 0f Which t-l1e traction or drive Wheels 6 arerevolnbly secureol. A longitudinally positionecl frame 7 is pivotallymounted upon the axle 5 between the traction wheels and extenclsforwardly thereof. T0 the rear end 0f this frame a transverse bar 8 issecured and l1as attached acljacent to its ends the scraper plates 9Wl110l1 engage with the periphery 0f the wheel and re1nove tl1e cli1twhich acoumulates thereon. The bearing sleeves 10 of the frame 7 may beprovided with suitable roller bearings t0 prevent frietion therein asthe driving axle is rotated. 011 the rear transverse bar of the frame 7a vertical support 11 is arranged upon the up- Specification of LettersPatent.

sleeve 14 loosely positioned cenrally on the axle. Tl1e diagonalsupporting bar is provided with the foot rests 15 upon which theoperator places bis feet.

Upon the forwarcl end of the longitudinally positioned frame 7 atransverse frame 16 is arrangecl. The forward longitudinal bar 0f thisframe is pivotally coimected to the side bars of the frame 7, as shownab 17. Tl1e tongue 18 extends over the frame 16 and is positionedbetween the bracket plates 19 which am secured upon the rear transversebar of the frame and a holt 20 extends thlough tl1e tongue and connectssaicl brackets. Adjacent t0 either end of the transverse frame a seedb0x 21 is mounted and is adapt-ed to deposit the seed into the dependingconducting tube 22 whicl1 is secu1eol ab eacl1 end to the oppositetransverse bars 0f the frame 16. Tl1e seed boxes are eacl1 provioleclwith the inwardly extending bottom plates Wll10h directs the seed intothe conclucting tubes. The runners 01 furrow openers 22 of the tubes areadapted to cnt into the seil in the usual manner t0 deposit the seecl atthe proper depth.

In oraler t0 intermittently drop the seecl I provicle the followingmechanism: At dia- 1netrically Opposite points upon one of the clrivewheels 6 a transversely extencling stud 01 arm 23 is securecl. Atransverse rock shaft 241 extencls centrally through the fra1ne 16 andis oscillatably mountecl in the encls thereof. T0 0ne end 01" thisshaf'o t-l1e arm 25 is securecl. This arm extencls rearwardly ancl hashinged t0 its encl a second arm 26 Which is aclapted t0 be engaged bythe t-iansversely extencling studs carriecl by tl1e tracti0n wheels. Thearm 26, however, is only aclaptecl t0 be engaged by tl1e studs t-0 dropthe seecl when the wheels 6 are rotating in one clirection as themachine is moving forwarclly. A vertically extending arm 27 is secureclt0 the shait 24 adj acent each end ancl carries an arcuate plate 28 towhich is secured the stud 29. This stud engages with the transverse arm30 formecl upon a sliclable seecl plate 31. This seeol plate is arrangedbeneath the bottom of the seecl box and is aclapted to be helcl in itsnormal position by means of the retraetile spring 32, tl1e forward endof which is secured to the furrow opening-shoe and itsother end 110fhe'seed plat'e. Thus it Will be ndted that as the drive Wheels rotateand the arms or studs 23 suc cessively en age Wih the arms 26, theupright 27 osc1lla t es as the stnd 29 is bronght' into engagment W1l3hthe' arm 30 wliereby' the seed plate Will boreciprocated and an openingtherein brought into alinexnent with the ope'ning formed by the inwardlyinclined bottom plates- 21' so that the seecl may fall through the sa1neand into the shoe. A shorb V rearwardly extending plate 25' extends fromtlie bottom of the arm 25 to and beneath the arm 26 Whereby theydownward movement of saiolaim is prevented. 1 In order to raise thefurrow open1ng shoe from the ground when it is deslred 't0. tu1n themachine and to regulate' th'e'planting clepth of the segd, I Provid6 aleve'r 33 which is pivotally Carried on tho rear end of. the tonguel8.This lever is in the form of a hell crank and. extends Tearwardlybetween theSpaced ears 14: formed uponthe central' sleeve14. The leveris provided with-a lon giqudinal slot 33"through whichfa tiansver'se pinconnecting' the ears 14: extends.

Thus the lever 1S adapted t0 have .sliding movement betwen the ears asthe same is operated to lift the transverse frame 16. 'Ihe l'ever isalso pivoted intermdiate' of its ends upon a raok segment 34 which issefi cured upon the centrzil sleeve 14 on alle axle 5.

Thus as the operators weiglit is all upon the rear part of thelongitudinal frame 7, when the leve r 33 is grasped and swung rearwardlyupon its p1V0t, the fiongue and trans- Verse frame 16 Will loe lifted.upon the pivot pins 17 and the furrow openirig shoes thus elevatd fromoontact with the ground. The operating lever, of coufse, carr1es theus'ual spring priessed manually' operat-ecl dog which engages with theteeth of the rack t0 seo1'1re the lever in its adjusted Position. Adoubletree 35is arranged upon tho tongue 18 and carries the swingletrees36 to which the draft animals are attached. The tongue is further bracedand 'supported from the transverse frame by 1nems 01: the diagonallyextend-' ing baics 37.

In order 'o provide suitable marking means Whereby the rows of cornhillsmay bei kept parallel as tl1e maohin6 is moved :Eiom end 110 end of thefield, I provide the' 1'0d 01 bar 38 Whioh is pivoted in a U-shaped Clip39 oarried by the rear transverse bar of th e.longitudinal frame 7. Thispivoted rod j is provided With a marking foot 4:0 which is adapted 130engagewith tl1e sur faoe of ehe ground and indioate an-intermediatepositin betweei1 the rows 0f corn hills. Thus 011 the return ti*ipof themachine one of the tractionwheels oan. bei -positi'oned on this line'somarkedand k e t in such position until the opposite end o th e fielclis reached, thuS planting the hills in parallel IOWS.

' 1. In a maohine of the character When*the marker iS not being used itmay be raisod' and supp0xte'd in an elevated position by means of theWire 411 which is couneoted to the upper end of a vertical stand- 'iifd4l2 secured to one of the longitudinal -fret'me bars of the main frame 7From the foregoing it is believed that theoperation and ncianyadvantages of my improved corn planter Will be obv1ous with- 01113requiring a niofe extended description.

The .varions parts are 'entirely automatic in their operation and arepositively aotu ated to intermittently dro 3 the corn ab Suitableintervals. It Will, 0 couise, be underv stood that a reater number 0foho transversely extening studs 23 may be provided upon thetracti0nwheels whereby tl1e corn dropping mechanism may be operated a1:shoi*ter'or longer intervals as desired.

Tho entire forward part of tl1e maohine may be quickly elevated by themanipulation of the lever33 without requiring a grat amount of exertionupon alle art of the operatcir, as bis weight g1*eatly assists incounterbalanoing the weight of the feed boxes and furrow opening sh0es.

Coinparatively few arts are employed in the Construction of ehe machineand it Will, therefore, be obvious that the expense of manufacture isreduced to a minimum.

While I havo shown and described what I believe to be the preferredembodiment of the invention, it will be understood that nu- Y merousminor modifications may be resorted to without deparzting from theessential fea tures or saor1ficlng any of the advantages thefeof.

I-Iaving thus described the invention whatis claimed is: d

'by one of the drive wheels adapted to engage said arm to rock theshaft, means carried by ehe shaft engaging withk said seed plates toreciprocate the same when the shaft is rocked, means for preventing therotation of said shaft upon the reverSe movement o f the drive wheelsand a spring counected to each 0f the seed plates toreturn the same t0its normal position af'ter the seed has been dropped.

2. In a machine 0f he character described, the comb ination with awheeled 'frame, of a.. transverse frarne pivotally 1nountedbeneath theforward; end of said wheeled frame, a transversely extending rock shaftmounted on said transverse frame, a seed b0x carried by said frame aboveeach end 0f the shaft, a reciprocatory seed plate arranged in the bottomof each of said boxes and adapted to deposit a predetermined amount ofseecl, a vertical arm securecl to each end of said rock shaft adapted t0engage with the seed plates 110 reciprocate the same', an arm extendinglaterally and rearwardly from 0ne end 0f the rock shaft formecl in twohinged sections, studs carried by one of the drive whee1s engaging therear arm s'ection to rock the shaft and reciprocate said seed plates,and a spring secured t0 each 0f the seed plates adapted to return thesame to its normal position after the seed has been dropped.

8. In a machine 0f the eharacter described, the combination Wih anoscillatory wheel supported frame, of a transverse frame pivotallymounted beneath the forward end of the wheeled frame, a roch shaftcarried thereby, seed boxes arranged on said frame above each end of therock shafb, a reciprocatory seed plate arranged in the bottom of each 0fsaid boxes having an opening therein, a transversely extending armformed 0n each of said seecl plates, a vertical arm carried by the rockshaft engaged with the arm of said seed plate, an arm extenoL inglaterally and rearwardly from one end of the rock shaft, said arm beingformed in two hinged sections, the rear section being supported by theextremity of the ot-her section against independent downward movement,outvvardly extencling studs carried by one of the drive wheels engagingthe rear arm section t0 rock said shaft and reciprocate the seed platest0 permit of the deposit of the seed through the openings therein, and aspring secured to the forward end of each 01 said plates and adapted oreturn the Same t0 their normal positions after the seed has beendropped.

In testimony whereof I hereunto afiix my signaourein the presence of twowitnesses.
